To @ZZ vw/'tormz'z may concern:

Be it known ,that I, LEROY S. Prou'rs, a citizen of the United States, residing at Can'- ton, in the county of Stark and State of Ohio, have, invented certain new and useful improvements in and Relating to Filling -Mechanism7 of which the following is a specification. p lThis invention relates to filling mechanism, and more pa ticularly to valve con struction for controlling the filling of a receptacle such as the freezing cylinder of an ice cream freezer.

For the purpose of illustration, I have, in the accompanying drawings shown and herein described one form of apparatus embodying my invention.

Figure l is a side elevation of a liquid .freezing Iapparatus embodying my invention, parts being broken away. Fig. 2 is a section on the line 2-2 of Fig. 3.. Fig. 3 is a top plan view of the liquid holding, tank and parts associated therewith, the freezer being omitted. Fig. 4 is a section on the line li-li of Fig. 2. Fig. is a fragmentary view l of the inlet member.

For the purpose of disclosing one embodiment of my invention, I have selected to illustrate it in connection with a self emptying `brine ice cream freezer of the horizontal type.

in the drawings, 1 indicates as an entirety a freezer which is mounted on a suitable vsupport 2. At one end, the support 2 may be provided with brackets 2, 2, the former supporting a shaft for gearing 3, rand the latter supporting a drive-means, such as a motor 1i. The motor 4: is preferably connected by belting-a silent drive chain for instance-*With the main gear 3 of the y gearing 3.

The freezer l preferably comprises an inner cylinder la and an outer cylinder 1* spaced from the inner cylinder` 2", c indicate thefront and rear heads,

respectively, of thel freezer. The front head 2b may comprise an annular niemb ri2b and and surrounding a-n opening `formed in the cover 2. The wall terminates in a hori zontal plane, and the opening therethrough may be closed by a pivoted cap 2g.

The rear head 2c is formed with a central Patented July d, i916.

bearing opening 2cl through which extend the shafts 5, 45M, of the material agitating mechanism 5. The shafts 5, 5M, are driven by gearing 3 inopposite directions as will be understood by those skilled in thisart. The heads 2b, 2, are each provided with annular bosses 2 (only one being shown) which form seats for the opposite ends of the cylinders l, 1* and also serve to space them apart. Between the cylinders l, l, a circuitous brine way la is provided, this way being connected at one end with a brine supply pipe 6.

2h is an inlet duct for material, carried by the head 2 and communicating at its inner end with the interior of the freezing cylinder, its outer end terminating in a horizontally disposed port 2*" surrounded by a screw threaded section 2h.

7 indicates a tank for holding a batch of material to be frozen. The tank 7 is preferably of rectangular shape. It may be removably supported by legs 7 upon the top of the freezer. The bottom of the tank 7 is inclined toward one end, preferably the rear end, to facilitate emptying of the tank, in the manner to be presently described. At its front end, the tank 7 may be provided with a transparent plate 7b by means of which the height of material in the tank 7 can be readily seen.

The freezer construction above described in itself constitutes no part of my presentinvention.

8 indicates a conduit leading from the latch tank 7 to the freezer inlet duct 2h. The discharge port or opening of the con- `duit 8 preferably extends into this freezer inlet duct. The conduit: 8 preferably comprises a vertical, tubular tapered section 8, openA from end to end, and an inclined section 8b, the outer end of which leads into and through one side wall of the vertical section. The inner end of the section 8 leads through the adjacent side of the tank 7 and forms the outlet duct therefrom. The sections 8, 8", are preferably formed in one piece of substantially,T-shape. Thelower en'd of the vertical section 8 and the upper end of the duct 2h may be connected together tir" in any suitable way, but y. preferably .by a

y'pair of 'detachably coupling members, Se, 8d.

9 indicates a hollow "cyiindrical member rotatably mounted Within*V the vertical section 8a. The member 9 is open from end to end and preferably extends upwardlyto or beyond the upper edge ofthe tank 7. The member 9,servesias an inlet conduit to per-v Vmit fruits'a-nd other tlavoring material to be 'at '9), to snugly fit the bearing surfaces formed by the inner walls of the vertical section 8a. l1 indicates a port formedin the wall 9" of the funnel member 9. The port 1l is arranged to register with the outlet end of the conduit section 8b when the fun? .nel member 9- is in one position-see Figs. 2

and d; in this position it permits the liquid in the batch tank to flow therefrom, through the conduit section 8b into the funnel member 9, which conducts the material down-V wa'rdly into the duct 2, and it in turn conducts the material to the freezer; but when the funnel member is rotated in its bearings the walls of said member close the passageway through the conduit 8. From this con` struction. it will be seen that the walls of the conduit member 9 and its. port il constitute a valve and the walls of the vertical section 8nl a valve seat to control the flow of the material from the tank 7, through the conduit S to the freezer l; it will also be seen that the lower portion of the inletrnember 9 also forms a part of the conduit 8 when its port y 11 registers with the section 8l. With these parts in this position, material may be introduced through the funnel 9 at the same time that the material is iowing from the batch tank to the freezer.

l2 indicates devicesfor 'rotating the funnel member to open and close the passageway 8. The operating devices' l2' preferably comprise anarm 12EL which isiixed to the member 9, and one or more links 12b which extend to a point within easy reach of the operative. Where the conduit 8 leads into the rear head 2 of the freezer-1,' `as shown in the drawings, a pair of pivotally connected-together links 12b', 12""- may be yprovided, the latter extending approximately to the front end of the freezer land being slidably supported at one side of the tank 7 by a pair of brackets 12". By moving the link 12" endwise, the conduit member 9 may be rotated in its bearings to open and close 'the `raive.

ln Aoperatiomtheyaive :tor the conduit 8 a batch, tank, ot a conduit3 formed in secmeegaan is closed; thereupon the batch tank is I illed with the liquid material which has been mixed for freezing. At the same time the motor 4 is .started and the agit-,ating mechanism 5 in the freezer 1 is rotated. The brine is admitted into the brine-wayla. The "combined funnel and valve member 9 is then rotated to bring its valve port l1 into registry with the conduit section 8b, whereupon the `liquid material Hows through the valve and conduit 8 to the freezer l. At the proper time, the cover 10 is raised and the fruit or otherk tiavoring material is poured into the of the freezer'with the proper materials, and l reduced materially the cost of manufacture.

The combined funnel and valve member 9 is preferably extended downwardly through the conduit 8 to a point beyond the connectionI of the section 8a with the duct 2h in order to eliminate completely all possibility of leakage, through the coupling 8c, 8d.

To those skilled in the art of making apparatus of the class described, many aiterations in construction and widely differing embodiments and applications of my invention wiil suggest themselves, without departing from the spirit and scope thereof. My disclosures and the descriptions herein are Apurely.illustrative and are not intended to be in any sense limiting.
